vTo all whom t may concern.' n Be it Aknown that l, VVILLIA'M lVAL'rnnSiri-rien, a citizen of' the United States, re-

siding` in the citar7 of' Portland, in the county of Jay, State ofIndiana, have invented a new andv useful vConci'ete-lt`i1iislii1ig'Machine, of' which the following is a full, clear, and comprehensivespecification and exposition, being suoli as will enable others to vmakeand use the same with'exactitude.

The object of my present invention, broadly speak-ing, is to provide aconcrete finis-hing,` machine which is comparatively simple incharacter, strong` and durable in construction, positive in its results,easily operated and controlled', automatic in its several actions, andwhich canbe manufactured and sold at a comparatively low price.

More specifically stated, my obj-ect is to especially adapted forconcrete roadways, the same being adapted to be driven thereby andarrangedto automatically accomplish three vdistinct operations or re-',sults at one time, namely: Striking off,

tam-ping, and belting,l whereby when the concrete compost is deliveredin front of the machine the machine completely finishes the roadwaywithout the employment of manual labor applied thereto.

@ther mino-r objects and particular advantages of the invention willsuggest themselves in the course ofthe following' description, whentaken in connection with the accompanying drawings, and that which isnew will be correlated in the` appended claims. Y

The preferred means for carrying out the principles of my invention in apractical manner is shown in the accompanying drawings in whichFigure 1is a top plan View of the entire machine.v Figure 2 is a front elevationof the same. Figure 3 is a righthand end elevation of the same., Figure4 is a rear ele ration of the same. Figure 5 is a leftehand eleva-tionof the same'. And Figures 6 and 7 are detail, views of the guide arm forthe meansv by which the beltingstrip is carried.

Similar indices denote like parts through` out the several views.

ln order that the construction', the operation, and the severaladvantages of the nvention may be more fully understood and appreciatedl will now take up a detailed description of the same, in which I willset frame, which is braces 5 by power carried .i

- of the machine.

forth the various features Ythereof as fully and as comprehensively as lmay.

rlhe framework of my construction comprises the front sill 1, the rearsill 2, and therightv and left end sills 3 and. l, respectively,.all ofwhich are rigidly connected at their ends forming a parallelogram-shapedretained in shape by the and 6 rigidly secured thereto as shown.

j The central portion of the base frame just. mentioned is supported bytwo arched bents 7 and 8, whichare secured at their ends to the ends ofthe respective sills 1 and 2, eX-

tending` thereover throughout their lengths.

The bent 7 is rigidly connected with the sill 1 by the vertical posts 9,10, 11, 12 and 18. Likewise the bent 8 is connected with the sill 2 bythe posts 14, 415, 16, 17 and 18.

intermediate sills 19,20 and 21 connect the sills 1 and` 2.

Q; a 1f 1 M I eecui eu underneath each of the corners ot the base frameabove described is a hanger, as the hangers 22., 23, 24 and 25, in whichare revolt/ablymountedl the respective carryingwheels 26, 27, 28. and29, which are adapted to roll forward and rearward 'to carry the device.rlhe wheels 28 and 29 are connected by the shaft 30, the central portionof which operates in the hanger 31 which extends downfrom the sill 2 tocarry said shaft. n The power plant comprises a conventional motor 32,which has a shaft 33 by which power is delivered from the motor to openate the parts ofthe machine.

A bevel pinion 3l is secured on the projecting' end of the shaft 33.,for the purpose herein set forth.

Cross bars 35 and 36 are secured to the sills 19lalid 20, the formerbeing` near the center and' the latter near the forward side Carried bysaid cross'bars, and extending` upward therefrom, are therespectivepedestal bearings 37 and 38, which carry the revolvable shaft39., rlherea-r end of said shaft carries 'the bevel gear 40,'

A'

rl`he blade TT is providetl with pueh-arnts 90 and 91, thev forward endsof which are forked to provide an upper and a lower linger, and they arepivoted to swing laterally by means of the bearings 9.2 and 93.respectively, which bearings are rigidly secured to the back of theblade 77. The rear ends of said arms 90- and 91 are mounted to the undersides of the cross sills 19 and 21, respectively, each by a compound,double, er universal bearing, 94 and95, re-- spectively. Said armjsafford great strength to positively push the blade forward, but at theVsame time permitting the blade to have lateral movements, whichmovements are attained as follows: .A pivot 9G extends back from therear of the blade 77, and a link 97 extends between and 1s mounted onthe pivot 96 and the wrist-pin 75, as in Fig. 2, whereby the rotation ofthe shaft 58 will lcause the blade 77 to move alternately to the rightand the left.

I will next describe the tamping mechanisin: Numeral 98 denotes thetampingbar, which is disposed underneath and extends almost the fulllength of the machine from right to left. Secured to and extendingupward from the bar 98 are two guidepins 99 and 100, which are adaptedto slide up and vdown through apertures therefor in the respectiveguide-blocks 101 and 102. Said guide-blocks are carried by therespective crossbars 35 and 52, from, which it is apparent that the bar98 has only vertical movements with relation to the machine, but ofcourse it has a forward movement as it is carried along wi-th'themachine.

Extending` upward from the vsills19-and 21 are the pedestal bearings 103and 104, respectively. Extending between and rotatably mounted in saidbearings is the shifting-shaft 105, whichk is adapted'to be slightlyturned by means of the handle 105 secured thereto. A smaller shaft 107extends longitudinally of and through the shaft 105 but it is locatedeccentricallyr thereof as shown in F ig. 3, and it is adapted to revolveindependently of the shaft 105. Pitman-heads 108 and 109 are mounted onthe shaft 107 and adjoining the outer sides of the bearings 103 and 104,respec tively.

Secured to and extending down from the respective heads 108 and 109 arethe pitmans 110 and 111, whose lower ends are hinged to the bar 98.Secured on the projecting left end of the shaft- 107 adjoining thepitman-head 109, is the gear wheel 112, which is adapted to mesh withthe largergear wheel 113, which latter is secured on the left end of theshaft 44.

It will now be seen that the revolving of the shaft 44 will result inrevolving the shaft 107, thereby causing the pitmans to alternately mpveup and down, thereby imparting up and down movements to, the tamping-bar98.

The belting mechanism comprises a rod 114, extending the length of themachine, onL the rear side thereof, and its end portions extend downwardand then directly rearward forming the fingers 115 and 116, for thepurpose hereinafter stated. Said rod 114 is mounted t0 slide endwise androtatably in the bearings 117, 118 and 119.

Numeral 120 denotes a non-rotatable bearingthrough which the rod 114extends, the rod 114 being provided with a projecting pin `121 which maymove in the. slot 122 formed through the bearing 120, as in Fig. 1,whereby the rod 114 and the bearing 120 must always move endwisetogether, yet permitting the said rod to have a limited rotary movementindependent of the bearing 120, which miovement. is limited by tnelength of the slot 122.

l Rigidly connected to the bearing 120 is a guide or bearing arm 123,which first extends direct-ly forward from said bearing and then extendsupward @and rearward at an angle to near the underside of the sill 2where it again extends directly forward in contact' with the undersideof said sill. this last forward portion being adapted to slide laterallyin a slip 124 carried by the underside of the sill 2.

Numeral 125 denotes a pitman, .one end of which is mounted on thewrist-pin 76, and its other endv being mounted on the lower horizontalportion of the member 123.

By this arrangement it will be seen that as the shaft 72 revolves. itwill, by means of the pitman 125, cause the rod 114 to slide endwise,alternately to the right and the left.

Extending between and secured at its ends to the fingers 115 and 116 istheI canvas or belting strip 126.

Attention is called to the fact that the bearings 22, 23, 24 and 25 areadjustable laterally, that is they may be moved inward from that shown,as the bolts bywhich they are secured may be changed to other holesformed in the sills, thereby adapting the machine to operate in makingroadways` of various widths.

The wheels 25, 27, 28 and 29 are adapted to trav-el on tracks A and Bplaced on each side of the proposed roadway and which are the same asordinarily used to form the side edges of th-e roadway and by which theroadway is leveled or finished to grade.

In practice the proposed roadway is excavated to the desired depth, andthe side rails A, and B, are located so that their upper edges will beat the grade line to which the roadway is to be made. My machine is thenmounted on said rails, as shown, and with the motor running, then theoperation will be substantially as follows: The concretey mixingmachinerst travels forward between the raila Ji and l and delivers the desiredainonnt ol cement compost hetween .fiaid nils. ne lever el may now heShift-:fd to notch a which will, aa explained. cante the niachine totravel il'orward7 hnt quite 5lowly, whereh)Y the in'evionsllv depositedconlliost will first he engaged h v the hlade l?, which not only nievesforward with the niaehine hilt it will have an endwiee inovenientalternating to the right and the lett and in addition thereto it willhave a third inovenient: Tfirst one end and then the other end moving'in advance.
